Sternchen - Star-Shaped Ornament

Now that we're in the middle of November, Christmas decorations are starting to be seen again. To get into the right mood, I tried to a knit small 3-dimensional star. And once I finished one, I couldn't stop and did quite a few more - because they really look cute and it's fun knitting them.
Even though these stars are 3-dimensional they are knitted flat. They have six points, are constructed of short rows and knitted (nearly) all in garter stitch. They come in four sizes and can be used to decorate your house for Christmas.
As to the name, "Sternchen" is the German word for little star.

The pattern is available as a PDF on Ravelry here.

• a written pattern for all four sizes

In order to knit one of these stars, you need the following knitting skills:

• Grafting in garter stitch

Materials

To knit these stars you need

• yarn - leftovers will do, when using fingering weight yarn, I used about 5 grams of yarn to knit a bigger star, with Sports weight it was about 10 grams
• straight knitting needles - I used a size that was a bit too small for the yarn to get a tight texture
• crochet hook and scrap yarn for provisional CO
• stuffing - I used old yarn ends that I had collected from my last knitting projects
• a tapestry needle for grafting and to weave in ends
• one stitch marker
